Messaging
MMS
MMS (Multimedia Messaging Service) is expected to
become the preferred messaging method of mobile
phone users since there are virtually no limits to the
content of an MMS transmission. An MMS message can
contain text, graphics, animations, images, video, audio
clips and ring melodies. For third party developers’
information, please visit www.SonyEricsson.com/
developer/ and look for the MMS developers guidelines.
MMS completes the potential of messaging. Sending
digital postcards and PowerPoint-style presentations is
expected to be among the most popular user applications
of MMS. Eagerly awaited by young users in particular,
MMS is projected to fuel the growth of related market
segments by as much as 40%.
Multimedia Messaging uses WAP (Wireless Application
Protocol) as bearer technology which can also be
powered by the high-speed transmission technology
EDGE/GPRS. This allows users to send and receive
messages that look like PowerPoint-style presentations.
The messages may include any combination of text,
graphics, photographic images, speech and music clips.
MMS will serve as the default mode of messaging on all
terminals, making total content exchange second nature.
From utility to sheer fun, it offers benefits at every level
and to every kind of user.
OTA configuration
Users can easily get MMS into their phone. MMS
supports OTA, meaning that the user does not have to
configure the settings manually. The configuration is
done by the operator.
MMS objects
Although MMS is a direct descendant of SMS, the
difference in content is dramatic. The size of an average
SMS message is about 140 bytes, while the maximum
size of an MMS message is about 200 Kbytes (limited by
both the memory capability of the mobile phone and less
than ideal network conditions), enabling much richer
MMS content. Complete with words, sounds and images,
MMS content is endowed with the user’s ideas, feelings
and personality. An MMS message can contain one or
more of the following:
Text
As with SMS and EMS (Enhanced Messaging Service),
an MMS message can consist of normal text. The length
of the text is unlimited. The main difference between an
EMS and MMS message is that in an MMS message,
text can be accompanied not only by simple pixel images
or melodies but by photographic images, graphics, audio
clips and video clips.
Templates
The phone comes with a number of MMS pre-defined
templates, for example templates for birthday cards,
meeting requests etc.
Audio
MMS provides the ability to send and receive audio as
part of messages. The phone supports iMelody, MIDI,
and AMR formats. Not only can users share a favorite
song or ringtone with a friend, they can also use the
mobile phone to record a sound or message and send it
along with a text message. As sound includes speech as
well as music, this extra dimension to an MMS message
allows for a spontaneous and immediate personal
